Book: in beginner guide change irc channel #rust → #rust-beginners
I also would like to add the reference on the first README.md
Some like
```
most popular channel is [#rust], a venue for general discussion about
-Rust, and a good place to ask for help.
+Rust. And a good place to ask for help would be [#rust-beginners].
[IRC]: https://en.wikipedia.org/wiki/Internet_Relay_Chat
[#rust]: irc://irc.mozilla.org/rust
+[#rust-beginners]: irc://irc.mozilla.org/rust-beginners
```
So In the first page would be the two options for #rust or #rust-beginners

/# This is a combination of 16 commits.
/# The first commit's message is:
allow RUST_BACKTRACE=disabled to act as if unset
When RUST_BACKTRACE is set to "disabled" then this acts as if the env.
var is unset.
/# This is the 2nd commit message:
case insensitive "DiSaBLeD" RUST_BACKTRACE value
previously it expected a lowercase "disabled" to treat the env. var as
unset
/# This is the 3rd commit message:
RUST_BACKTRACE=0 acts as if unset
previously RUST_BACKTRACE=disabled was doing the same thing
/# This is the 4th commit message:
RUST_BACKTRACE=0|n|no|off acts as if unset
previously only RUST_BACKTRACE=0 acted as if RUST_BACKTRACE was unset
Now added more options (case-insensitive): 'n','no' and 'off'
eg. RUST_BACKTRACE=oFF
/# This is the 5th commit message:
DRY on the value of 2
DRY=don't repeat yourself
Because having to remember to keep the two places of '2' in sync is not
ideal, even though this is a simple enough case.
/# This is the 6th commit message:
Revert "DRY on the value of 2"
This reverts commit 95a0479d5cf72a2b2d9d21ec0bed2823ed213fef.
Nevermind this DRY on 2, because we already have a RY on 1,
besides the code is less readable this way...
/# This is the 7th commit message:
attempt to document unsetting RUST_BACKTRACE
/# This is the 8th commit message:
curb allocations when checking for RUST_BACKTRACE
this means we don't check for case-insensitivity anymore
/# This is the 9th commit message:
as decided, RUST_BACKTRACE=0 turns off backtrace
/# This is the 10th commit message:
RUST_TEST_NOCAPTURE=0 acts as if unset
(that is, capture is on)
Any other value acts as if nocapture is enabled (that is, capture is off)
/# This is the 11th commit message:
update other RUST_TEST_NOCAPTURE occurrences
apparently only one place needs updating
/# This is the 12th commit message:
update RUST_BACKTRACE in man page
/# This is the 13th commit message:
handle an occurrence of RUST_BACKTRACE
/# This is the 14th commit message:
ensure consistency with new rules for backtrace
/# This is the 15th commit message:
a more concise comment for RUST_TEST_NOCAPTURE
/# This is the 16th commit message:
update RUST_TEST_NOCAPTURE in man page

Book: Fix phrasing: “an associated type” → “an object with an associated type”.
From what I understood, `graph` is the object from which we create a trait object, and the associated types are `Graph::N` and `Graph::E`.

doc: "mut" not needed for the examples

While implementing panic_fmt for the GameCube I noticed that the parameters given to it were completely broken. Turns out that panic_fmt requires the C ABI to work correctly. This should be fixed in the documentation, so that others don't make the same mistake. Thanks to mbrubeck in the IRC for helping me figure this out.
Not specifying extern for lang_items correctly should potentially also be a compiler error.

docs: make some text changes on Section `Macros`
(1) In contrast to `that`, `so that` expresses `result` indicated by the sentence, not `reason`;
(2) `block` is an expression, and may be have an expression, so I add `optionally an expression` to make more precise;
~~(3) When I read here, I was confused with what `the child` referred to. After modification, it would be better.~~

Remove trailing whitespace at the end of lines
According the rules of styling Rust code there should not be trailing whitespace at the end of lines or files. I thought that it might be good to remove trailing whitespace from other files also, if it does not break anything.

Docs: Change "statements" to "expressions" on `match`
I apt to use `expressions` over `statements`, because `match` is a expression in essence, though it can become a statement when followed a semicolon.

docs: Make some changes in texts
In my understanding, the description is somehow inappropriate.

docs: Correct an improper description
In the example, we made a immutable borrow to `println!`, not a mutable one.
|

Update of the book; Error handling, section on custom error types: we…
… should also show the changes to the `cause` method.
When I started creating my own error type, I found that we also have to update the cause method, otherwise we have a missing match branch.
It would also be nice to elaborate on the relationship and difference between the description() and fmt() method, but that should be done by someone with more experience with them. :)

docs: `let` introduces a statement
I changes *expression* to *statement* to make more accurate, because in Rust, `let` introduces a declaration statement.

Add a link validator to rustbuild
This commit was originally targeted at just adding a link checking script to the rustbuild system. This ended up snowballing a bit to extend rustbuild to be amenable to various tools we have as part of the build system in general.
There's a new `src/tools` directory which has a number of scripts/programs that are purely intended to be used as part of the build system and CI of this repository. This is currently inhabited by rustbook, the error index generator, and a new linkchecker script added as part of this PR. I suspect that more tools like compiletest, tidy scripts, snapshot scripts, etc will migrate their way into this directory over time.
The commit which adds the error index generator shows the steps necessary to add new tools to the build system, namely:
1. New steps are defined for building the tool and running the tool
2. The dependencies are configured
3. The steps are implemented
In terms of the link checker, these commits do a few things:
* A new `src/tools/linkchecker` script is added. This will read an entire documentation tree looking for broken relative links (HTTP links aren't followed yet).
* A large number of broken links throughout the documentation were fixed. Many of these were just broken when viewed from core as opposed to std, but were easily fixed.
* A few rustdoc bugs here and there were fixed

Remove inaccurate claim about inline assembly
It's not like GCC's.

Small grammar fix in Guessing Game
When it was Option.expect(), there was an .ok().expect(), but now that it uses Result.expect(), there's only one method, not two.
Fixes #31912

Remove final note from testing chapter.
The information that documentation tests cannot be run in binary crates is already given at the beginning of the section.
